Subdivision Surface Tesselation on the Fly using a versatile Mesh Data Structure

Kerstin Müller, Sven Havemann
2000 Computer graphics forum (Print)  
Subdivision surfaces have become a standard technique for freeform shape modeling. They are intuitive to use and permit designers to flexibly add detail.  ...  But with larger control meshes, efficient adaptive rendering techniques are indispensable for interactive visualization and shape modeling.  ...  At this point, subdivision surfaces can actually be seen as an adaptive rendering method for a mesh.  ...

Multilevel Design for the Interior of 3D Fabrications

Kanygul Chynybekova, Soo-Mi Choi
2019 Symmetry  
This article presents a multilevel design for infill patterns. The method partitions an input model into subareas and each subarea are applied with different scales of infill patterns.  ...  Our approach allows for the composition of sparse and dense distributions of patterns of interior 3D fabrications in an efficient way so users can fabricate their own 3D designs.  ...  Furthermore, we provide detailed descriptions of the designed subdivision schemes for each presented pattern.  ...

Geometric Parameter Control of Infill Patterns

Chynybekova
2019 Designs  
The proposed approach is applicable for many different patterns, including linear pattern designs.  ...  The variations of infill pattern design are useful for creating more lightweight and stronger 3D fabrications.  ...  The above described subdivision schemes have different purposes, the interpolating subdivisions mostly used for the controlling shape while the approximating schemes are used for smoothing curves.  ...
